At her first wedding held in Monaco last August, Tatiana rocked the hippy look, wearing a flowing ivory Missoni gown with a garland of flowers wrapped around her head. She then changed into a bespoke, floor length, white lace Valentino dress inspired from the 2013 Resort Collection for the reception.
For her winter wonderland wedding in Switzerland next month, Tatiana is expected to wow the crowds once more and has chosen a show-stopping, fairytale Valentino gown to take centre stage. Fashionistas and royal watchers dying to see Tatiana's dress won't have to wait much longer, as the Colombian beauty will say "I do" to her Prince Charming on 1 February.
Tatiana's decision to wear Valentino may not come as a surprise as the mother-of-one is a known admirer of the Italian designer. A regular at Paris Fashion Week, Tatiana has been spotted sitting front row at Valentino's shows and the pair are often pictured enjoying each other's company at high-profile events.

In keeping with Tatiana's romantic vision, the couple will wed in a candle-lit ceremony at 7pm in the 11th century convent of Rougemont. With their vows exchanged, Tatiana and Andrea will leave for a wedding dinner at the Palace hotel in a horse-drawn carriage, wrapped in white furs.
The couple's second wedding will take place over the whole weekend, with guests arriving on the Wednesday before.
